REFRIGERATOR CAR.

Application led. May 21, 1923. Serial No. 640,411.

The accompanying drawings illustrate the preferred form of theY invention, though it is to be understood that the'invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings;

Fig. 1 is a. partial vertical section partly broken away, of a refrigerator car constructedrin accordance with this invention;

Fig. 2 is a horizontal section through part of the side and end walls ofthe strucf ture shown in Fig. 1;

Fig. 3 is a horizontal sectionI on Aan enlarged scale of a wall ofthe structure shown in Figs. 1 and 2 taken at a post and showing the manner'of securing the insulating layers which form the walls;

Fig. 4 is a view similar to Fig. 8 and sh'rwing a,modi1ied construction of wall; an

Fig. 5 is a view similar to Fig. 3 and showing a further modification of the wall construction. Y

It is an object of this invention to provide a refrigerator car of improved construction and more particularly to provide a refrigerator car wherein the heat insulating material constitutes the walls of thecar and reenforces the posts and braces in carrying the wall strain. It is also an object oi this invention to provide an insulating wall which is comparatively light and of great strength and which may; be quickly and cheaply made and applied. It is also an object of this invention to provide a refrigerator car wall without the usual dead airspaces thereby decreasing the wall thickness and increasing the car capacity.

As shown in the drawings, the car comprises the usual underfrarne having the center sills 1 and the side sills 2 joined by body sills are secured the Z-shapedy side posts 5 and braces 6 while to the end sill 7 are secured the end posts 8 and at the corners are secured the angle corner posts 30, the upbolsters 3 and cross bearers 4. To the side .plurality of sheets or layers 12 of cellular fibrous material which has been thoroughly matted or elted in the manufacturing process and pressed into rigid self-sustaining sheets of light weight and capable of carrying considerable loads. The layers 12 are protected by a layer 13 of suitable water proong material'. rlthe heat insulating e5 material 12 is set in a short distance from the sides and ends of the floor 10 in order to provide space for the nailing strips 14 upon which is placed the main Hoor 15. The floor 15 is spaced from the insulating 70 material 12 a suitable distance so that nails used in securing objects to the floor 15 will ynot puncture the Water proofing 13 and the lnailing strips 18 to which is securedthe wood ceiling 19 upon which are placed a plurality of layers 12 of the heat insulating 80l material. The layers 12 upon ythe ceiling are held in position by strips L20 which are en gaged by the carlines 21 secured to the posts 5 and supporting the roof 22.

The construction of ,the side and end walls is identical. Referring more particularly to a side Wall, each wall comprises a plurality. of layers 12, of which the layers a and b are placed between the furring strips 17 and the posts 5 and extend outside the nailing strip 90 14 to, engage with the sub-floor 10 at-the side sills. At its upper edge the inner layer b extends in back of the fascia plate 9 while the outer layer a; stops just short of the fascia plate, leakage fromV the fascia plate into the wall being prevented by the water shed 23 which extends from between the fascia plate and the layer b of heat ini sulating material beneath the fascia plate and projects downwardly a short distance in front the outer heat insulating layer a. These two layers of heat insulating material have staggered joints, the joints in each instance coiningin back of one of the posts and the layers being secured together at the post by nails which are driven throughthe two layers and clenched. i

The 'urring strips 17- are shouldered as at 24 and extending between the :Earring strips are a plurality of layers of heat insulating material, there being as shown in F ig. 3, the two layeis 0 and d, which are held in engagement with the outer layers a and b by the shoulders 24 of the furring strips and which are secured to the outer two layers by nails.

The layei's e and ,f extend between` the turring strips and are held in position by the layers g and it which are nailed to the furring strips. As shown in Fig. 3 the layers g and 71, of heat insulating material also have staggered joints, the joints in each instance coming in line with the urring strips so that the edges of the sheets of insulating material may be properly secured to the furring strips.

1n the modification shown in Fig. 4 the inner layer it of heat insulating material is replaced by a wood sheathing 25 which is provided to protect the heat insulatiznflr material from the contents of the car. t:In the modification shown in Fig. 5 the furring strip 170 is not shouldered and some of the layers of heat insulating material l2 are replaced by layers 26 of hair felt or similar material 'clamped in place by the urring strips while the inner layer of heat l,insulating material is replaced by theAV wood sheathing 25 as in Fig. 4. In each case, however, all the' layers with the exce tion of the two outer layers a and b extend etween the floor 15 and wood ceiliner 19 and have their edges secured by the nailing strips 27 and 28.

1t will be seen that this invention provides a car wall in which there are no dead air spaces and which is composed substantially entirely of heat insulating material and which in conjunction with the posts and braces will withstand the usual strains to which a car wall is subjected, the laminavtions or layers 12 of heat insulating material being sufliciently rigid and strong to be selfsustaining and to contribute materially to the strength of the ear walls.
